Water is a marvellous gift of god weather it is being used for household or in construction. One cannot think of concrete without water. Whether you make a concrete or perform curing, the water is a chief role model of concrete. While you make a concrete, a fixed amount of water is needed, but the amount of water needed for curing is not fixed.

there is no exact quantity on how much water u should sprinkle on the structure once u start curing the concrete… The sample once it settled at 24 hrs after casting, is immersed to the curing tank until the time of testing (28 days). From there u can deride that the structure should be all throughout wet to attain the needed strength at 28 days.

![What Is Water Cement Ratio? Its Calculation [Complete Guide]](/tupian/54.jpg)
This is another defect of extra water added to concrete-mix. Water Quantity Calculation for Concrete. For the calculation of water quantity for concrete, first of all, we have to find the quantity of cement. Just assume that the required volume of cement for the mix is 100 kg and W/C is 0.4. Water Quantity = Water-Cement Ratio x Volume of Cement.

Concrete mix ratio of 1:3:3 – On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened. The strength concrete is inversely proportional to the water/cement ratio.
